“With a single packet, an attacker can become root on a remote machine by simply removing the authentication header.” ‘ Unfortunately, Microsoft can’t fix it for you. Users affected by these vulnerabilities must manually update the OMI agent to the patched versions.

Microsoft on Tuesday addressed a quartet of security flaws as part of its Patch Tuesday updates that could be abused by adversaries to target Azure cloud customers and elevate privileges as well as allow for remote takeover of vulnerable systems.

The list of flaws, collectively called OMIGOD by researchers from Wiz, affect a little-known software agent called Open Management Infrastructure that’s automatically deployed in many Azure services

Open Management Infrastructure (OMI) is an open-source analogous equivalent of Windows Management Infrastructure (WMI) but designed for Linux and UNIX systems such as CentOS, Debian, Oracle Linux, Red Hat Enterprise Linux Server, SUSE Linux, and Ubuntu that allows for monitoring, inventory management, and syncing configurations across IT environments.

“Once operational, the MQ-25 will refuel every receiver-capable platform including E-2,” Reed said in a separate news release on the August flight test between T1 and the Navy’s Air Test and Evaluation Squadron Two Zero (VX) 20. “This flight keeps us on a fast track to getting the Stingray out to the fleet where its refueling capability will greatly increase the range and operational flexibility of the carrier air wing and strike group.”

The first aerial refueling test was conducted on June 4, when an F/A-18E-F Super Hornet refueled in air with the unmanned tanker for the first time in naval aviation history. In this first in-air encounter with the drone, a Super Hornet approached to take measurements, made several “dry connects” to practice connecting and detaching from the tanker, and made two actual refuelings, with 300 pounds and then 25 pounds of fuel being passed from the Stingray to the Super Hornet at different altitudes and flying conditions.

Last month, the Navy and Boeing conducted in a virtual environment the first manned-unmanned teaming event between the Stingray and a Super Hornet, where the manned jet bypassed the ground control station and communicated directly with the tanker drone to give directions on where and when to rendezvous for a refueling.

Since the spread of virus causing COVID-19 continues, experts recommended wearing homemade facemasks when surgical or N95 masks are not available to prevent the spread of the pandemic. While such makeshift masks are more economical and accessible in low-capita countries, the effectiveness of cloth masks has not been studied in depth.

In Physics of Fluids, researchers from the Indian Institute of Science studied the fate of a large-sized surrogate cough droplets at different velocities, corresponding from mild to severe, while using various locally procured fabrics as masks.

“Our results show cotton, towel-based fabrics were most effective among the considered fabrics and must be stitched together as multiple layers for making homemade facemasks,” said author Saptarshi Basu. “A three or more-layered homemade mask is recommended, since it can suppress aerosolization significantly.”

A Science Immunology analysis of patient samples collected before the #COVID19 pandemic shows that killer #Tcells that can recognize #SARSCoV2, despite never having encountered the virus before, are located in tissues, rather than circulating in blood.

Tissue-resident memory CD8+ T cells in unexposed oropharyngeal lymphoid tissue exhibit specificity for SARS-CoV-2.

Every piece of data that travels over the internet — from paragraphs in an email to 3D graphics in a virtual reality environment — can be altered by the noise it encounters along the way, such as electromagnetic interference from a microwave or Bluetooth device. The data are coded so that when they arrive at their destination, a decoding algorithm can undo the negative effects of that noise and retrieve the original data.

Since the 1950s, most error-correcting codes and decoding algorithms have been designed together. Each code had a structure that corresponded with a particular, highly complex decoding algorithm, which often required the use of dedicated hardware.

TEPCO has been repeatedly criticized for coverups and delayed disclosures of problems at the plant. In February, it said two seismometers at one reactor had remained broken since last year and failed to collect data during a powerful earthquake.

TOKYO (AP) — Officials at Japan’s wrecked Fukushima nuclear power plant have acknowledged they neglected to investigate the cause of faulty exhaust filters that are key to preventing radioactive pollution, after being forced to replace them twice.

Representatives of the operator, Tokyo Electric Power Company Holdings, made the revelation Monday during a regular review of the Fukushima Daiichi plant at a meeting with Japanese regulatory authorities. Three reactors at the plant melted following a massive earthquake and tsunami in 2011.

The filters are designed to prevent particles from escaping into the air from a contaminated water treatment system — called Advanced Liquid Processing System — that removes selected radioactive isotopes in the water to below legal limits.
